Claims

[Scope of Claim for Utility Model Registration] Equipped with a collector, a storage tank, and a pump, on the suction side of the pump, a first suction pipe that sucks hot water from the storage tank, a second suction pipe that also sucks low-temperature water, and both. A switching valve is provided for the suction pipe, while an outgoing pipe extending to the collector via the first on-off valve and a returning pipe from the collector to the storage tank are provided on the pump discharge pipe side. A differential temperature thermostand is installed that detects the drop in pressure and opens and closes the first on-off valve based on the detection signal, and a pressure detector that detects a drop in pressure and operates the pump based on the detection signal is installed on the pump discharge side, and a pressure detector that detects the flow. A pump discharge/hot water supply pipe is provided which extends to the faucet section via a float detector and an auxiliary heat source which actuate the switching valve in response to a detection signal of the perilla, and a second on-off valve and a A return pipe leading to the storage tank via a check valve is provided, and a drop in the temperature of hot water in the pipe is detected in these pump discharge/hot water supply pipes or the return pipe, and the pump and the second on-off valve are operated in response to the detection signal. A solar water heater equipped with a thermo stand.
